Good day Humphrey!
Is it okay if I will
ask some help from you? As this point in time, I am repairing a Samsung tv-21
inches. The trouble is when you switch the power to ON position, there is a
raster, and then after about 2 seconds, it changes to blue color- a video
signal
Display I think and
vice versa. I re-soldered the video amplifier at CRT, and the jungle ic,
no changes happened.
Humphrey:
Usually if the TV has no antenna it behaves like this, So first make sure the
antenna is installed and the connector to the TV set is ok(the rf connector)
If the
antenna is well set and still don’t get the audio or the video then you can now
start troubleshooting the set.
For the
symptoms you have mentioned (no audio and no picture) the best place to start
your troubleshooting is the tuner circuit.
Refer
to chap16 of your eBook for more info on this circuit and for a live example of
how I solved such a problem refer to chap 27 about the Sony TV I repaired with
the similar symptoms in the same book.
All the
best Gary.
Gary: Thank you for your
advice and suggestions.
I have started
reading your eBook and I would say it's really a big help to me. Although, I am
a graduate of one-year electronics course, I still need to know more about TV
repair and thanks for your eBook.
Humphrey: Thanks Gary for your positive feedback… Wishing you
all the best my friend
Regards Humphrey
